IBEATER, WHIPPER, MIXER, AND MAST-IE3 FOR EGGS, GREAT/I, VEGETABLES, 85c.

To all whom it may concern:

Be it known that I, WVILLIAM STURMA, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Beater, \Vhipper, Mixer, and Masher for Eggs, Cream, Vegetables, &c., of which the following is a specification.

My invention consists in providing a heater, whipper, mixer and masher for eggs, cream, vegetables, etc, with means whereby the beating member may receive motions that may be either gyratory or simply rotary in the plane of its axis according to the nature of the work to be accomplished.

For the purpose of explaining the invention, the accompanying drawing illustrates a satisfactory reduction of the same to practice, but the important instrumentalities thereof may be varied,'and so it is to be understood that the invention is not limited to the specific arrangement and organization shown and described.

Figure 1 represents a perspective View of a beater etc. embodying my invention. Fig. 2 represents a vertical section of a portion thereof, certain members being in a different position from that shown in Fig. 1. Fig. 3 represents a partial top view and partial horizontal section on line 0cw, Fig. 2. Fig. 4 represents a partial side elevation and a partial vertical section of a detached portion. Figs. 5 and 6 represent views respectively vertical and horizontal of detached portions.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings :A designates the frame of the machine, the same having secured to its lower portion the ring B, in which is supported the pan B, the latter being adapted to contain the material to be beaten, whipped, mixed, mashed or otherwise worked.

C designates the main shaft, the same being vertically mounted in the upper portion of the frame A and receiving power from any suitable source, in the present case, the bevel gearing D, the shaft E, the pulley F, the belt G and the wheel H. The shaft C is formed in sections C, C the adjacent ends of which are adapted to be coupled,

they being formed respectively with the tongue and groove J, K, which are adapted to engage and receive the pm L, thus con- Specification of Letters Patent.

necting the sections as one, see Figs. 2 and 4, but when said pin is withdrawn, said sections are disconnected, and may be separated, as shown in Fig. l. The lower end of the section C has connected with it the semi-circular yoke M, which is adapted to rotate with said section. The upper end of the section C is mounted in the journal box N, which is fitted within and swingingly attached by the pivot N to the yoke P, the latter having connected with it the rods or stems Q, which project outwardly in opposide directions from said yoke P and are fitted freely in eyes R on the lower terminals of the yoke M. On the shaft section below the yoke P, is the ball S whose lower portion has its bearing T of the form of a half socket supported on the horizontallyarranged arm U, which extends from and is secured to an adjacent member of the frame A. The upper portion of the ball has its bearing in a half-socket \V, above which latter is the cap V, which covers the same. Below the socket or bearing T is the oildrip cup X, which is properly secured to said ball S. The ball S has an upward continuity of the form of a split sleeve S, in which and said ball the section C is freely fitted, said sleeve having its members adapted to be compressed to the proper extent upon said section by the bolt and nut S The cap V is firmly secured to said sleeve S by the screw S which passes through the same and the adjacent portion of said sleeve. In the upper face of the. bearing T is the recess T, which freely receives the gudgeon T which is adapted to rock in said recess as the ball S oscillates in its bearings. Connected with the lower end of the shaft section C is the beating member or beater proper Y, which enters the pan B, and is adapted to operate therein. The bearing N is provided with ears \V, by which it is screwed or otherwise secured to an adjacent support U on the frame A, and so retained stationarily in position, said bearing having in its top an enlarged opening centrally therein for the play of the adjacent portion of the sleeve S during the oscillations of the shaft section C and corresponding motions of the ball S.

The operation is as follows :Should it be desired to cause the beating member Y to oscillate or sweep around the interior of the pan B, the pin L is withdrawn and the screw R loosened. The yoke P is now moved in lateral direction, in the present case to the right, and the rods Q move correspondingly through the eyes R, and the shaft section C is placed at an inclination, the screw It then being tightened, said screw passing through one end of the yoke lit and having its point engaging the adjacent portion of the rod Q. The screw S is also tightened so that the split sleeve of the ball clamps the shaft section 0 thus depriving the latter of independent rotary motion on itself. The position of parts being shown in Fig. 1, motion is communicated to the shaft section C, and by it to the yoke M, the yoke P, box I and shaft section C said box oscillating with said yoke P, while said section, and consequently the beating member Y, are in inclined position. The ball S oscillates in its bearings, sustained to some extent by the gudgeon T which has free rocking motions on the wall of the recess T, and so the beating member Y is held in in clined position and thereby sweeps around the inner sides of the pan without rotating on itself, whereby it acts to whip the material in the pan, thus causing an effective working of the same. As the ball oscillates, the gudgeon T will rise and fall to a limited extent, the rise being permitted by the slot or recess T in the periphery of the upper bearing IV of the ball, said recess being above the recess T and registering therewith.

In some cases, the material requires to be beaten, etc. by simply rotary motion of the beating member Y. In this case, the screw It is loosened, and the shaft section C moved into engagement with the shaft section C, when the two sections are coupled by the pin L, the yoke P and connected parts moving with the section C the latter now being centered in the pan.

The screw S is operated to release the split sleeve of the ball from its holding action on the shaft section C when the latter is free to rotate within said sleeve and ball. The screw It is also tightened, the several parts assuming the positions as shown in Fig. 2. Power is now applied to the shaft, when both sections C, C rotate as one, while the ball S remains stationary in its bearings. The beating member Y thus rotates on itself within the pan on its vertical axis without oscillating or sweeping around the pan, as in the case when the parts are in position, Fig. 1, the effect of which is the working of the material by rotary motion from the center of the pan.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
